In early 1994 Good Samaritan Medical Center and Bethesda Hospital, now Genesis HealthCare System, jointly agreed to co-develop an EMS system designed not only to meet the needs of the hospitals but to also serve the citizens in nearby communities with emergent medical care and transportation. While the county was well served with several Volunteer EMS services (and remains so even today), the City of Zanesville was facing the closing of two of its long time EMS providers.In 1997, Genesis HealthCare System agreed to sell 25% of CAS to Community EMS of Southfield, Michigan. Like CAS, CEMS is a not for profit organization and owned by a healthcare system.

Throughout CAS' existence CEMS had been contractually responsible for the day-to-day operations of the business. Extending ownership to CEMS seemed appropriate to ensure a long-term relationship between the two companies

Today our service has expanded to include Springfield Twp. and the Village of South Zanesville. Not all of our business is EMS related though. We also provide transportation to those confined to a wheelchair through our Ambulette service. Additionally we also have developed a Courier service specifically intended to meet the needs of Genesis HealthCare System.
